F1: Travel to fixed stop
6.2 General functionality
Basic Functions
318 Function Manual, 09/2011, 6FC5397-0BP40-2BA0
Example:
Block-related limit (FOC)
The parts program command FOC activates the torque limit for a block.
An activation from a synchronized action takes effect up to the end of the current parts program block.
Priority FXS/FOC
An activation of FXS with FOC active has priority, i.e. FXS is executed.
A deselection of FXS will cancel the clamping.
A modal torque/force limitation remains active.
After PowerOn the activation takes effect with the machine data:
MD37010 $MA_FIXED_STOP_TORQUE_DEF.
This torque can be modified at any time by programmingFXST.
Synchronized actions
The language commands FOC, FOCON, FOCOF can also be programmed in synchronized actions as the
commands for "travel to fixed stop."
Determine FOC status
The activation status can be read at any time via the status variable $AA_FOC.
If FXS is also activated, the status is not changed.
Determine torque limit status
The system variables $VA_TORQUE_AT_LIMIT can be used at any time to read in systems whether the
currently active torque corresponds to the given torque limit.
N10 FOCON[X] ; Modal activation of the torque limit
N20 X100 Y200 FXST[X]=15 ; X travels with reduced torque (15%)
N30 FXST[X]=75 X20 ; Changing the torque to 75%.
; X travels with this reduced torque.
N40 FOCOF[X] ; Disable torque limit
0: FOC not active
1: FOC modal active
2: FOC block-related active
0: Effective torque less than torque limit value
1: Effective torque has reached the torque limit value
